Specification of Letters Patent.

Application filed March 21, 1914. Serial No. 826,380.

To all whom, it may concern Be it known that I, SIMEON F. PIERCE, a citizen of the United States, residing at St. Paul, in the county of Ramsey and State of Minnesota, have invented certain new and useful Improvements in Generators, of which the following is a specification.

My invention relates to improvements in generators for generating gas from heavy hydro-carbon liquids as kerosene, its object being particularly to provide means for cleaning out the generator when the flame is extinguished.

To this end the invention consists in the features of construction, combination, and arrangement of parts hereinafter described and claimed.

In the accompanying part of this specification, Figure 1 is a side elevation of a street lamp, broken away, fitted with my features of invention; Fig. 2 is a vertical section through the generator and adjacent parts broken away; Fig. 3 is a section on line ww of Fig. 2; Fig. 1 is a section on line yy of Fig. 2; and Fig. 5 is a vertical section of the needle.

Referring to the drawings, A represents a generator casing of a burner. The burner is formed with a central mixing tube 2. A plug 8 is inset in the bottom of the tube 2 and formed with a jet orifice 4, a needle valve 5 being slidably supported in the bottom of the burner to extend into said orifice as shown in Fig. 2. The slidable support for the needle valve is secured through the medium of the transverse pin 6 projecting through a spiral slot 25 in the wall of the surrounding casing. The mixing tube is open at its lower end.

The generator is connected with a source of fuel supply through the medium of the following parts: 7 represents an inlet tube drawings forming for the hydro-carbon, a vaporizing chamber 8 being shown supported upon the outlet end of the tube. The chamber 8 is filled with movable parts 9, as shot, for the purpose of removing the carbon in the well known manner. The chamber 8 at its upper end is connected by a port 10 with a second chamber 11 communicating with the inlet port 12 of the generating chamber 13 extending around the mixing tube. The generating chamber 13 is connected by a downwardly and laterally extending conduit 14: with a jet opening 4. A deflector flange 15 surrounds the mixing tube below the generator 13 for the purposeof deflecting the flame against the generator. The generator casing is formed with an open topped tube 16 sur rounding the upper end of the mixing tube and spaced therefrom, a plurality of subflame openings 17 being formed in the wall of the casing between the mixing tube and the lower end of the surrounding tube 16. Arranged over the tube 16 is a usual type of mantle supporting hood 18 formed with a central opening 19.

For the purpose of carrying out my invention I include within the pipe 7, which leads from the supply tank 20 to the generator, a relatively large reservoir 21, the reservoir as shown in Fig. 1 being positioned at or about the height of the port 12 leading into the generator. I also form the feed tube 7 with an upward extension 22 alongside the generator, a being supported at the top of the tube 22 at or about the height of the inlet port 12.

The chamber 21 and the dome or chamber- 23 cooperate with the burner in the following described manner: When in use the hydro-carbon liquid is used to an extent that brings the'top of the liquid to about the top of the chamber 21. The lowering of the gas pressure due to the dropping of the gravity head will result in the flame becoming extinguished. The contents of the chamber 21 will by gravity then pass through the conduit 7 out through the jet opening 4 dropping to the collector 2 1. As this liquid passes through the generator parts, including the chambers 8 and 11, it will flush or clean the collection from the balls, and otherwise within the generator chambers, carrying the same through the jet opening to the collector and leaving the generator and jet opening clean.

The chamber 23 performs the function of cleaning out the generator and the function of steadying the flame. As it is filled with the liquid hydro-carbon from the inlet tube 7 the air in the top of the chamber will be compressed, and this compressed air acting upon the hydro-carbon liquids helps to steady the flame.

If a feed tube of the size shown in the drawing is employed without an associated chamber 21 or chamber 23, the lowering of the liquid hydro-carbon in the feed tube by lowering the gravity head will, as in the dome or chamber 23 construction shown, cause the flame to be advantages of my combination by a rela-;

extinguished. After the flame is extinguished there will still be some liquid in the tube to run through the generator, but it will not be suiiicient in quantity to flush out the generator, but on the other handwill be of such small amount as to be hardened by the retained heat in the generator, clogging up the generator and jet. If on the other hand, the feed tube. 7 is made larger than shown, it willresult in too large a flow of fluid through the generator. I secure the tively small feed tube 7 and large chamber 21 or 23. I claim as my invention:

1. An oil burner of the class described comprising a generator, a reservoir positioned above said generator, a tube leading from the reservoir to the generator, and a relatively large oil storagechamber inset in said tube at a point outside the heat radius Copies of this patent may be obtained for five cents each,

of the generator and above the oil inlet thereof for the purpose set forth.

2. An oil burner of the class described comprising a generator, a reservoir positioned above said generator, a tube leading from the reservoir to the generator, and a relatively large oil storage chamber inset in said tube at, a point outside the heat radius of the generator and above the oil inlet thereof, said tube passing into and out of the opposed upper and lower ends of said chamber to cause said chamber to constitute in its entirety a storage enlargement of the passage way from the reservoir to the generator.

r In testimony whereof I affix my signature in presence of two witnesses.
